Front

What is the rule for transforming coordinates to create similar figures?

Back

To create similar figures, you can apply a scaling rule to the coordinates, such as (kx, ky), where k is the scale factor.

Front

What does a scale factor of 2.5 indicate when comparing two rectangles?

Back

A scale factor of 2.5 means that the dimensions of rectangle 2 are 2.5 times larger than those of rectangle 1.

Front

What are corresponding sides in similar figures?

Back

Corresponding sides are the sides of similar figures that are in the same relative position and have the same ratio of lengths.

Front

How do you determine the scale factor between two similar triangles?

Back

To determine the scale factor, divide the length of a side of one triangle by the length of the corresponding side of the other triangle.

Front

What is the transformation rule for moving a figure right 5 units and down 3 units?

Back

The transformation rule is (x + 5, y - 3).

Front

If the coordinates of a figure are (x, y), what would be the coordinates after applying the rule (0.75x, 0.75y)?

Back

The new coordinates would be (0.75x, 0.75y), indicating a reduction in size by a factor of 0.75.

Front

What is the difference between congruent sides and corresponding sides?

Back

Congruent sides are sides that are equal in length, while corresponding sides are sides that are in the same position in similar figures.

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but may differ in size, meaning their corresponding angles are equal and their corresponding sides are proportional.

Front

How can you find the coordinates of a figure after a transformation?

Back

To find the new coordinates after a transformation, apply the transformation rule to each original coordinate.

Front

What is the significance of corresponding angles in similar figures?

Back

Corresponding angles in similar figures are equal, which helps establish that the figures are similar.
